Objectives : The oral health education for interaction between snack and oral health is made more in detail, it seems to contribute to improvement of oral health by reducing occurrence of dental caries. Methods : This study performed the survey for 530 high school and college students living in Y City, Chungbuk for 10 days from June 14, 2011 to understand the difference by the level of snack recognition. 530 copies of questionnaire were collected, the final 502 copies were analyzed and the results are as followings. Results : 1. As for the snack intake frequency, 'sometimes' and '2~3 times a day' was found to be largest with 32.0% respectively in female and 'sometimes' was largest with 34.9% in male. As for the '2~3 times a day' was most in high school students with 31.5% and 'sometimes' was most in college students with 39.0%. 2. As for snack characteristics, 'crispy' was most preferred in female and male with 43.7% and 39.4% respectively and, by school year, high school students and college students preferred 'crispy' most with 39.1% and 46.0% respectively. 3. As for the item of meal, 'sometimes skip' was most in female with 46.1% and 'all three meals a day' was most im male with 51.4%. 'All three meals a day' was proved to be most with 48.3%in high school students and 'sometime skip' was most in college students with 48.0%. 4. As for the difference of oral health management by school year, college students (
) proved to be higher in the oral health management (p<.01) than high school students (
) and the Negative snack recognition group (
) was found to be higher in the oral health management (p<.01) than the Positive snack recognition group (
). Although the interaction between school year and snack recognition level was not different in case of college students, the Negative snack recognition(
) proved to manage higher oral health (p<.05) than the high snack recognition gathering (
) in case of high school students. 5. As for the difference of the oral health most im male wex and). Although the innteractifemale (
) proved to most the oral health (2.(p<.01) than male (
) and the group with Negative snack recognition terac (
) most d the oral health (2.(p<.01) than the group with Positive snack recognition level (
). As for effects of interaction between sex and snack recognition level, while there was not much difference in the oral health management by the snack recognition level in case of female, the cluster of low snack recognition level (
) proved to manage the oral health more (p<.01) than the gathering of high snack recognition level (
). Conclusions : To see the results as above, it can be seen the oral health management is higher as the snack recognition level is higher by sex and school year.

Objectives : In general, the active of volatile compounds which become usually known as the principal ingredient of bad breath is closely connected with temperature. In this study, an investigation was made into the correlation between oral malodor and the temperature of rinsing water. Specifically, an analysis was made of saliva in rinsing water with relation to amount, flow and pH. In addition, a calculation was made of O'Leary index. The results are expected to be basic data for oral malodor reduction plans. Methods : A total of 30 women who are in their 20s without any systemic disease and teeth braces and non-pregnant were chosen for the study. The research was carried during 3 weeks from 28 Mar to 11 Apr in 2011. Results : Saliva was not significantly affected by the temperature of rinsing water, in connection with saliva amount, saliva flow and saliva pH. The O'Leary index and oral malodor was the highest in warm water, but the subjects preferred rinsing with cold water. Conclusions : In conclusion, oral malodor was found to be reduced in inverse proportion to the temperature of rinsing water. Thus, it is recommended to rinsing water with warm water after tooth brushing.

DOI : 10.13065/jksdh.2012.12.3.471
Objectives : This study looked at the relationship between occupational stress and the Oral Health Impact Profile (OHIP), to evaluate the effect of occupational stress-related factors. Methods : Data was obtained from a cross-sectional survey of 260 local officials in Gangwondo. The research comprised three questions relating to subjective oral symptoms, an occupational stress measurement tool and an oral health impact factor which was composed of questions. The data was analysed using t-test, one-way ANOVA, Pearson correlation and path analysis in Amos. Results : Occupational stress had a positive correlation to drinking frequency, Oral symptoms had a negative correlation. And drinking frequency, smoking amount and occupational stress had a positive correlation to oral symptoms. It denoted that drinking frequency, occupational stress and oral symptoms had a negative correlation to OHIP. The path model had an excellent goodness of fit (p=0.07, namely p>0.05). Five 'goodness-of-fit indices' of the model were all above 0.9: GFI=0.987, AGFI=0.952, NFI=0.902, IFI=0.939, CFI=0.934), and its RMSEA was 0.045. Occupational stress and oral symptoms had a firsthand impact on OHIP. In addition, it affected OHIP through the parameters of oral symptoms. Occupational stress exercised a firsthand influence on drinking frequency, drinking frequency exercised a firsthand influence on smoking amount. Smoking amount had a firsthand impact on oral symptoms. Conclusions: Oral health education programs for the development of an improved oral hygiene environment through reduction in drinking and smoking also need to focus on relieving stress by improving workplace culture. In addition, due to good communication is required to reduce occupational stress caused by interpersonal conflict.

DOI : 10.13065/jksdh.2012.12.3.503
Objectives : This research seeks to present the data needed for the development of coping strategy, following medical market opening by identifying dental hygienists' perspective and coping measures towards the opening. Methods : One hundred eighty-eight dental hygienists were targeted to identify their level of perception towards medical market opening, attitude towards medical market opening, question of whether they agree or not with the opening and reasons, and coping measures and benefits of the medical market opening. t-test, chi-square test and cross-tabulation analysis were used for the analysis Results : First, team leaders are more aware of the medical market opening and hold greater sense of crisis towards opening compared to the rank and file. Second, the reasons cited for agreeing with the medical market opening included improvement of medical services' quality and diversification of services. As for the reasons for disagreeing, they cited the increase medical expenses paid by public. Third, limitation of the hospital management technique was cited the most when it comes to the scope of Korean hospitals' management crisis, followed by the limitations of the diagnosis procedure, limitations of the medical services, limitations of the medical techniques and increase in the number of large hospitals, in the order cited. Fourth, team leaders perceive greater need to seek coping measures from the aspect of realizing medical insurance fee from the policy development, service and system level aspects when it comes to the coping measures depending on their ranks. Conclusions : Therefore, Dental Hygienist has a comparatively low awareness of medical market opening, coping measures need to be explored to cope with the medical market opening by ensuring the dissemination of accurate knowledge through the education on the fees for dental hygienist and seminars in relation to the medical market opening.

DOI : 10.13065/jksdh.2012.12.3.513
Objectives : In this study, contact angle and shore D hardness were measured, and a shark fin test was conducted after selecting five addition silicon(Blu-Mousse, BM; EXABITE II, EX; PERFECT, PF; Regisil
Rigid, RE; Silagum
, SI) in order to figure out the properties of elastomeric interocclusal recording materials and reduce errors at interocclusal recording. 8) Methods : A contact angle was measured using a contact angle analyzer. After placing a drop of liquid on the surface of the specimens of interocclusal recording materials, a contact angle was photographed with a CCD camera on the equipment. In terms of a shark fin test, interocclusal recording materials were mixed for the time proposed by the manufacturer and inserted into the split ring of the Shark fin device. Twenty (20) seconds exactly, a metal rod was removed to make the materials slowly absorbed. Once they hardened, fin height was measured with a caliper after separating molds and trimming the specimens. The shore D hardness was measured with a shore D hardness tester(Model HPDSD, Hans Schmidt & Co. Gmbh, Germany) in sixty (60) minutes after fabricating specimens. In each experiment, five specimens, mean and standard deviation were calculated. A one-way ANOVA test was performed at the p>0.05 level of significance. In terms of correlation among the tests, Pearson correlation coefficient was estimated. For multiple comparison, Scheffe's test was carried out. Results : A contact angle was the highest in EX with
(p<0.05) while the result of the shark fin test was the longest in RE with 5.45mm. SI was the lowest (0.27mm) with statistical significance. Among the interocclusal recording materials, significant difference was observed in terms of means (p<0.05). The shore D hardness was the highest in SI with 31.0 while RE was significantly low with 16.4 (p<0.05). Among the materials, statistically significant difference was observed in terms of means when compared to the rest materials (RE), BM, RE and SI (PF and EX) and the remaining materials (BM and SI) (p<0.05). In terms of correlations among the tests, a negative correlation occurred between shore D hardness and shark fin test(r=-0.823, p=0.000). Conclusions : According to the study above, it is necessary to understand the properties of interocclusal recording materials and consider contact angle, shark fin test and properties of shore D hardness to select appropriate materials.

DOI : 10.13065/jksdh.2012.12.3.521
Objectives : The aim of this study was to evaluate the relation between the state of dental health(number of natural teeth) and nutritional status of Korean elderly using Korean Dietary Reference Intakes, which was an objective standard for nutritional intake based on database of Korea National Health and Nutrition Examination Survey, large scale of sample obtained by the government. Methods : Complex sampling procedure was used to analyze the fourth data(2007-2009) of Korea National Health and Nutrition Examination Survey. When preparing planning file, the estimator of variance as a stratification variance (variance name : kstrata), population of survey unit as a cluster variance(variance name : PSU), and previous exam and nutritional related weighted as a weighted were analyzed by considering reproduced survey and nutritional related total weighted. Complex samples chi-square test was used to estimate the relation between number of natural teeth and inadequate intake and relation factors included in the model were analyzed by complex samples logistic regression analysis. Results : The group of edentulous had a higher risk to intake less nutrient, except calcium, riboflavin and vitamin C than recommended level comparing to reference group which had natural teeth more than 20(phosphate : OR=1.763; 95% CI=1.273-2.443, thiamine : OR=1.748; 95% CI=1.276-2.395, protein : OR=1.610; 95% CI=1.213-2.138). Conclusions : The number of teeth in Korean elderly over 65 years old had a relation with nutritional status in this investigation. Especially, intake level of nutrients was different between the edentulous group and the reference group. Therefore, dental health care is needed from young and middle age to keep health dental condition for through whole life as well as old age. Although the dental condition of the aged is not good, it is evitable to educate them about the relation between dental health and nutritional ingestion to take balanced nutrition, we think.

DOI : 10.13065/jksdh.2012.12.3.533
Objectives : The purpose of this study was to evaluate the effects of tooth bleaching agent contained 35% hydrogen peroxide on the color, microhardness and surface roughness of tooth-colored restorative materials. Methods : Four types of tooth-colored restorative materials, including a composite resin(Filtek Z350 ; Z350), a flowable composite resin(Filtek P60 : P60), a compomer(Dyract
AP ; DY), and a glass-ionomer cement(KetacTM Molar Easymix ; KM) were used in the study. The specimens(
) were made by using a customized acrylic mold. Each material was divided into two groups equally(n=40) : experimental group(35% HP) and control group(distilled water). 35% HP group was treated 30 mim/5 days for 15 days. Each 30 minute treatment session consisted of two 15 minute cycles of gel application with 20 second light exposure. The authors measured the color, microhardness, and roughness of the specimens before and after bleaching. The data were analyzed with ANOVA and T-test. Results : 35% HP group showed an apparent color change(
) than control group. In particular, DY and KM showed a noticeable color change and statistically significant differences(p<0.05). 35% HP group showed a reduction in microhardness. Z350 and P60 does not have a statistically significant difference(p>0.05), DY and KM showed a statistically significant difference(p<0.05). Percentage microhardness loss(PML) of control group was 0.6 to 5.5% in the group, 35% HP group was 6.6 to 34.6%. Roughness was increased in 35% HP group after bleaching. Especially DY and KM were significantly increased(p<0.05). Conclusions : Bleaching agents may affect the surface of existing restorations; therefore, they should not be used indiscriminately when tooth-colored restorations are present.

Journal of Korean society of Dental Hygiene, volume 12, issue 3, 2012, Pages 543~551
DOI : 10.13065/jksdh.2012.12.3.543
Objectives : School-age children have mixed dentition and are sensitive to dental caries. Their dental condition is more important as it is directly related with oral health in their life, and parents' attention and education are necessary as the children can not manage their oral health voluntarily. Methods : To evaluate the effect of parents' occupational status on the oral health of children, this study conducted a questionnaire survey and analyzed the results along with the results of oral examination with 952 students and their parents of an elementary school located in Ulsan conducting school oral health projects on May, 2009. Results : As dental caries prevalence rate recorded 33.7%, 56.8% and 66.9% in non-dual income, professional dual income and non-professional dual income families, respectively, the rate of children of dual income families was significantly higher than that of non-dual income ones (p<0.05). Conclusions : For professional dual income families, although working mothers contribute to economic stability, they took less time to care or to educate their children compared to no-working mothers so that they need to pay more attention to oral health of children. In addition, more interest to and education for children of non-professional dual income families showing relatively lower socio-economic level and lack of time for children, were also necessary in school projects on oral health education and prevention.

DOI : 10.13065/jksdh.2012.12.3.553
Objectives : The purpose of this study was to examine actual conditions of smoking and alcohol drinking behaviors among high school students, so that it could recognize possible harmful effects of smoking on oral health and could give positive motivations for students to quit smoking and drinking. Methods : This research was based on self-filling survey which 1,385 high school students in metropolitan area in Korea from September 5 to October 28, 2011. Surveyed data were analyzed by descriptive statistics,
-test and logistic analysis using SPSS WIN 12.0 program and its signification level was 0.05. Results : 1. As for smoking rate and drinking rate, boy students accounted for 11.6% and 25.4%, thereby having been higher than girl students(p<.001). It was the highest in over 180 cm(16.0%, 35.0%, p<.001) for height, in 60-under 70 kg for weight(13.4%, 23.5%, p<.001), and in a case of profession for mother's job(13.8%, 28.4%, p<.005). 2. The perceived oral symptoms had relationship with the less than 10 cigarettes of smoke (OR=2.41; 95% CI:1.31-4.41), more than 11 cigarettes of smoke (OR=3.16; 95% CI:1.42-7.00) and more than 1 bottle of alcohol (OR=1.75; 95% CI:1.00-3.06). Conclusions : This result implies that adolescents' smoking and drinking have correlation with oral health status, which makes uncomfortable sense felt given chewing along with the pain in teeth and gum. Based on the above findings, a school or community needs to reinforce education for preventing smoking and drinking and to offer environment available for practicing anti-smoking and anti-drinking plan, in order to reduce adolescents' smoking and drinking.

Objectives : The study enquires into OHB and its importance of preschooler mothers, based on perceived experiences of OHE. It also investigates mothers' sense of responsibility for children's oral health. The purpose is to enhance the effectiveness of OHE and its orientation. Methods : From April 20th to June 15th, 2011, 14 nurseries or preschools were randomly selected from childcare facilities of one gu(borough) in Busan. The objects of study are mothers of four to seven-year-old children. The collected survey data were analyzed using SPSS 12.0 for Windows. Results : 1. There is a statistically significant difference(p<0.01) in relations between the mothers' working status and perceived experiences on OHE. 2. On the survey about OHB practices, there are significant differences(p<0.001) in toothbrushing before breakfast, after meals, in three minutes and after refreshments Significant differences(p<0.01) are also shown in toothbrushing after eating fruits. 3. On the survey about the importance of OHB, there are statistical significances(p<0.001) in toothbrushing manner-rather than the number of it-toothbrushing in three minutes after meals and following the correct way of toothbrushing. There are also significant differences(p<0.05) in brushing teeth for more than three minutes. 4. There are significant differences(p<0.001) in mothers' periodic dental examination, children's periodic dental examination and training experience on children's toothbrushing. 5. On the survey about the sense of responsibility for children's OHE based on experiences of OHE, there is a significant difference(p<0.05) in that many replied OHEis "much-needed" regardless of their experiences on it. Conclusions : The results show that of infants' mothers, those with experience on OHE, have an accurate knowledge about toothbrushing, due to the effectiveness of the education. Both groups, however, replied that children's OHE is much needed, suggesting problems about the accessibility of the OHE.

Objectives : This study evaluated the changes in surface roughness of denture base resin according to the types of denture cleansers. Methods : A denture base resin(Vertex RS, Dentimax, Netherland) was used. Two toothpaste(Antiplaque, Bukwang, Korea; 2080, Aekyung, Korea) and a kitchen detergent(Trio, Aekyung, Korea) were used as a denture cleanser. The specimens were put on the V8 crossbrushing machine(Sabri enterprises, Downers grove, IL, USA) to reproduce toothbrushing and the toothbrushes were flat, round end and soft type. The surfaces of denture base resin specimens were observed by profilometer(SJ-400, MITUTOYO, Japan) and SEM(S-3000N, Hitachi Co., Ibaraki, Japan). Results : 1. According to the result of measuring surface roughness, there was statistically significant difference in Ra, Rq, and Rz(p<0.05). 2. As for Ra, Rq and Rz, Antiplaque toothpaste showed the highest roughness, and there was significant difference from other groups(p<0.01). 2080 toothpaste, Trio, and distilled water were classified as the same group. 3. According to the result of observation with the SEM, the surfaces of the Antiplaque toothpaste group after toothbrushing showed the greatest roughness, and the surfaces of 2080 toothpaste, Trio, and distilled water groups were rough in order. Trio and distilled water had the surfaces similar to those before toothbrushing. Conclusions : Studies to compare the efficacy of denture management methods and examine the effects of denture cleansers on denture materials will be helpful for dental hygienists and dentists providing patients with proper information and education. And it will be also useful for denture users' oral health.

Objectives : The purpose of this study was to examine the influential factors for the oral-health practice of adult workers and the relationship of their health-promotion life style to the factors of oral-health practice in an attempt to determine the impact of health-promotion life style. Methods : The subjects in this study were 160 workers who worked in Seoul, North-Jeolla and South-Jeolla Province, and were at the age of 20 and up. The survey was conducted from February 1 to July 20, 2011. Results : As for the relationship of the general characteristics of the workers to the factors of their health-promotion practice, gender made statistically significant differences to toothbrushing female (3.24), and there were statistically significant differences in education/concern according to more than college(2.72) scored higher academic credential(p<0.05). The group of the workers whose health-promotion life style was better in terms of all the toothbrushing(3.35), use of oral hygiene supplies(2.19), regular dental-clinic visit(2.70), dietary control(2.84) and education/concern(3.20) scored higher, and there were statistically significant differences in the factors of education/concern(p<0.05). Their health-promotion life style had an impact on regular dental-clinic visit among the factors of oral-health practice(p<0.05), and there was a positive correlation between health-promotion life style and tooth brushing, dietary control(p<0.05), regular dental-clinic visit, education and concern(p<0.01) the factors of oral-health practice. Conclusions : Workers should be stimulated to get into sound life habits to change their behavior, and they should be urged to improve their preventive health care, to get a dental checkup and ultimately to promote their health as well. Companies should take measures to accelerate the oral health promotion of workers and provide more dental checkup programs for them to be more concerned about their oral health, to promote their oral health and to maintain the best oral health.

Objectives : This study mean to confirm the antibacterial activity of a garlic extract widely culturing in our region and was to determine the effect of dentifrice containing 0.1% extracts of garlic on dental plaque and gingivitis in a double blind and clinical studies in 50 healthy adults aged from 20 to 22 years who provided a consent for their participation. Methods : The antibacterial activity was evaluated using triple distilled water and the Kirby-Bauer disk diffusion method and the minimal inhibitory concentration(MIC) against various pathogens for periodontal disease, such as P. gingivalis 381(ATCC33277), was estimated. The experimental groups classified according to the concentration of garlic extract used: 10,000ppm(A), 5,000ppm(B), 2,500ppm(C), 1,000ppm(D). Oral examination of subjects was performed through clinical periods and on day of baseline, 6, 12, 19, 25 days plaque index and gingival index were scored by Turesky' modified index and Loe & Silness index. After 12, 19, 25 days use of their respective dentifrices, statistically decreases of plaque index, gingival index were shown in both the experimental and the control group, respectively. Results : There was significant antibacterial activity in the "2,500ppm(C)" group against P. gingivalis 381. Experimental group exhibited significantly the lower plaque levels and the higher levels of gingival health by the use of the dentifrices contained extract of garlic from 6 days compare with control group(p<0.05). The degree of decrease was more significant on gingivitis level of the experimental group than the control group(p<0.05). Conclusions : This findings indicated that the oral products containing a garlic extract is effective in preventing and treating periodontal diseases, and has potential value in inhibiting periopathogens.

Objectives : The purpose of this study is to analyze the sterilizing effects of toothbrushes by administering bacteria into toothbrushes and reproducing the antibacterial effects using a microwave oven. Methods : The heads of four-row mid-strength toothbrushes were cut, put in a bacterial solution (
) for vortexing, and sterilized with microwaves for 0, 30, and 60 seconds. They were then moved into four tubes containing DW 10 ml and suspended in a vortex mixer for two minutes to separate bacteria from them. DW 9ml was added by 1ml of bacteria for dilution of
times. It was then administered to the BHI agar plate by 0.1ml and cultured at
for 24 hours. Total number of bacteria adhered to a toothbrush was obtained by multiplying the number of colonies by the dilution factor. The experiment was done in the first, second, and third step, being repeated in a normal temperature drier (
) after 5, 9 and 24 hours. Results : The results of the experiment revealed that the sterilizing effects were 95% or over. When toothbrushes were sterilized for 60 seconds, the number of colonies is about 11 after drying for 5 hours, 7 after drying for 9 hours and 2 after drying for 24 hours. The sterilizing effects reached 98% when the bacteria-administered toothbrush was sterilized for 1 minute after drying for 24 hours. Conclusions : The results demonstrated that toothbrush sterilizing by using microwave is a suitable way to prevent cross-contamination of toothbrushes by oral bacterial infection and thus easy to use at home. However, this study suggests that toothbrush sterilizing by using microwave should be limited within two times a week because the physical properties of toothbrush might be changed.
